BAL leveler size question

Looks like I may have jumped the gun when purchasing a BAL leveler. It says for 12"-15" wheels. That said, I put it around mine just to see and it 'looks' like it would work so I can't tell if they mean for 12"-15" with tire or wheel only? I think my wheel is only 8"

Here is a pic for reference. Right as it started to raise the PUP, I stopped as I don't want to cause any damage if this is not the way it should be.

You have it setup right but your tires are a bit small. This is fine because you will almost always be able to slide it under your tire. I have 15" tires and it can be a challenge at times. I would suggest that you bring along a small piece of wood or 2 to put in between the jack & the Tire to take up some slack.
